* Add compilation flags: -Wshadow -Weffc++ -pedantic -pedantic-errors * Delete implicit copy & move constructors & assignment operators in classes with pointer data members. * An exception to the above: Add default copy & move constructors & assignment operators for the Binary class. * Convert boolean RegEx operators to binary operators. * Initialize all members in all classes in ctors. * Let default ctor delegate to the converting ctor in Binary and RegEx * Don't change any tests except regex_test (as a result of the change to binary operators). Note: https://bugzilla.redhat.com/show_bug.cgi?id=1544675 makes -Weffc++ report a false positive in "include/yaml-cpp/node/impl.h".
